R35i Modular The R35i Modular uses OPTO-SIC technology to provide our highest level of performance in a modular encoder. This innovative technology minimizes components to increase product reliability in the smallest possible package. The R35i also provides optional brushless commutation outputs and the highest resolution data channels available in the industry. The enhanced slide lock mechanism automatically centers and gaps the encoder thus making installation simpler than ever before.

R35i Mounting Instructions - Dynamic lignment erify that you received the following items: Encoder Cover Setscrew wrench M2.5 or #2-56 Torx Head Mounting Screws with Captive asher CTION ---- ESD Precautions pply ---- CTION Motor Preparation Dynamic alignment requires a second motor to backdrive the target motor. Connect motor winding to channel 2 of an oscilloscope. Encoder Preparation IMPORTNT! Do not apply power to the encoder at this time. erify that the slide lock mechanism is fully extended and the setscrew is in the 3 o'clock position. This will put the index and commutation underneath the sensors within 10 mechanical degrees. (Figure 1) Step 1 lign encoder mounting tabs with mounting holes on the motor. Slide encoder onto the motor shaft until the encoder is resting on the motor endplate. (Figure 1) If encoder hub does not slide easily, check that the hub setscrew does not extend into the hub bore or that burrs are not present on the motor shaft. If either exists, remove encoder and correct fault. Step 2 Mount the encoder to the endplate by installing the supplied Torx head mounting screws with captive washer under the screw head. Secure mounting screws finger tight, allowing encoder housing to rotate. (Figure 2) Threadlocker 222 may be applied to screw threads to prevent screw from unthreading during operation. Step 3 Secure the hub setscrew with 20 oz-in torque. (Figure 3) CTION: Over tightening the setscrew will cause rinelling of the shaft making it difficult to remove encoder. onding of encoder hub is recommended for high speed or accel/decel operation of motor. (onding and Debonding Methods) 542543 Step 4 Install test cable to encoder for commutation alignment. pply power to the encoder. Connect commutation to channel 1 of oscilloscope with oscilloscope set for positive trigger on channel 1. hile holding encoder body firmly, back drive motor so that motor shaft rotates CC when viewing encoder pc board (500 RPM MX for 1 minute MX). Motor speed should be adjusted for constant velocity of the motor shaft. (Figure 4) Change: Initial Release Release-no. Created Responsible Released ersion Rev.

Step 5 Rotate housing until rising transition of commutation occurs at the zero crossing of the motor back-emf signal of winding. (Figure 5) Secure mounting screws with 30 oz-in torque. Push in slide lock mechanism. Step 6 erify proper alignment of commutation with back-emf signal of winding. If not aligned properly, stop back-driving the motor, pull out slide lock mechanism, loosen mounting screws and return to Step 5. Step 7 ond hub to motor shaft using recommended bonding method. (onding and Debonding Methods) Step 8 Remove test cable and install cover. (Figure 6) Install cable assembly. Encoder is now ready for operation. Encoder Removal Remove cable assembly. Remove cover. Pull out slide lock mechanism to installation position. Loosen hub setscrew (If hub has been bonded, see (onding and Debonding Methods) Remove encoder mounting screws. Remove encoder.
